A few days back, the machine got shut down forcefully due to power failure. getting this issue after that. Please suggest or let me know if any further details are required.

Worked after increaing the Java Heap size of name node

Name node process was exiting while loading the inodes. Since my last restart, I had created a lot of files on hdfs which lead to significant increase in inodes. But since my java heap size was not comaprable to that so JVM was pausing.
